parted -s "${diskpath}" mklabel gpt parted -s "${diskpath}" mkpart primary 1MiB 2MiB Isn't "primary" wrong here? It assumes your `mklabel` command used label-type of msdos or dvh. You are using gpt though. In case of gpt "primary" is a label, not a partition type. You can use a descriptive string here instead of "primary" (e.g. "boot partition", or "esp partition"). https://manpages.debian.org/unstable/parted/parted.8.en.html#mkpart https://manpages.debian.org/unstable/parted/parted.8.en.html...
